I have the same situation with the Elan Touchpad on my Acer laptop. The scroll wheel stops working each time Windows 10 updates anything. I have gone into Windows update and "told" it not to download drivers for other devices, but each time there is any update to Windows 10 it sees I have the old Elan driver and reinstalls the Windows 10 version of the driver. This is frustrating. Windows 10 download history shows that it downloaded and installed the wrong driver 27 times in the last 2 months. You'd think it would have figured out by now that it is the wrong driver. Any ideas anyone? It's a game: I reinstall the correct driver, then Windows 10 update reinstalls the wrong driver.
